An alcoholic goes into a bar and says, “Give me a drink before the trouble starts.”
The bartender gives him one. He drinks it, and says, “Give me another drink before the trouble starts.”
He downs that one, and says “Give me another drink before the trouble starts.” He drinks that, and says, “Give me another drink before the trouble starts.”
Finally the bartender gathers some courage and asks, “When’s this trouble going to start?”
The alcoholic says, “The trouble starts as soon as you realize that I don’t have any money.”
